JOHN OARLSON, OF MANDAN, NORTH DAKOTA.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent'No. 623,132, dated April 18, 1899.

Application filed February 12, 1898. Serial No. 670,098. .No model.)

To all whom it may concern:

Be it known that 1, JOHN OARLSON, ofMandan, in the county of Morton and State of North Dakota, have invented a new and Improved Acetylene-Gas Machine, of which the following is a full, clear, and exact description.

My invention relates to an improvement in acetylene-gas machines of that class in which the water is delivered in regulated amounts to the carbid for the generation of the gas.

The invention consists of certain novel features of construction, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a top plan view of my device. Fig. 2 is a side elevation thereof. Fig. 3 is a sectional side elevation thereof on the line 3 3 in Fig. 1. Fig; 4 is a sectional plan view thereof on the line 4 a of Fig. 3. Fig. 5 is a partial sectional elevation on the line 5 5 in Fig.4. Fig. 6 is a sectional elevation of the relief-valve placed at the top of the condenser. Fig. 7 shows the spider used to hold the removable head in its place. Fig. 8 is a section showing the cut-off valve by which connection may be broken by hand between the water-supply and oarbid-holder, and Fig. 9 is a perspective view showing one of the carbid-holders removed from the machine.

In my machine I make use of the ordinary bell-gasometer, with a water seal, which consists, essentially, of two hollow cylinders open at one end and placed one within the other in inverted positions, with water in the lower outer cylinder. This outer cylinder A, which forms one portion of the gasometer, has its outer shell extended below the partition a, which forms the bottom of the water-tank. In the lower chamber formed by the partition a is constructed a cylindrical chamber D, adapted to receive the 'carbid-holder. For convenience this chamber is constructed in cylindrical form, although the cylindrical shape is in no sense essential. This chamber D is connected by a pipe G'with the interior of the outer portion A of the gasometer, within which is placed the water which forms the seal. Within the water-tank thus formed is placed a valve H, closed by means of a lever H, provided at one end with a weight h, adapted normally to hold the valve closed. The cylinder A, which forms the outer portion of the gasometer and the water-tank, is supplied with sufficient water to keep the valve H immersed at all times. When the valve H is opened, water will flow through the pipe G and into the chamber D through the sprinkler-pipes g, which serve to scatter the water in the chamber. Within the chamber D is placed a carbid-holder E, formed as a cylinder having one side open. One end of the chamber D is extended beyond the outer casingAand is providedwith' an outwardly-extending flange ct, and this end of the chamber is closed by a removable head d. The head d is placed over the open end of the cylinder, with suitable packing material between the head and the flange a, and is clamped in position by means of a spider F, preferably made of three radial arms, two of which are provided with hooks F, adapted to engage the rear edge of the flange a, and the third is straight, entering beneath the loop or staple f'.'

Pressure is applied between the spider F and the head d by means of a hand-screw f,

which passes through the spider and bears upon the head D.

It is intended that at least two of these carbid-holders be provided for each machine, one of the holders to be filled before the other holder is removed from the machine, and the holder which has been removed is replaced by the filled holder.

The pipe G, connecting the water-tank with the chamber D, is provided with a valve G, by which the How of water may be stopped. A pipe G connects this valvewith the outer casing, and through said pipe extends a rod G connected to the valve G and provided at its outer end with a handle by which it may be turned by hand. When it is desired to remove one of the carbid-holders, the valve G is closed, thus cutting off the supply of water. The gas which has been generated in the holder E escapes into the gasometer through a pipe D, provided at its upper end with an automotic closing-valve D which will close and prevent any backflow of the gas.

The bell B, forming the movable part of the gasometer, is provided with a central upwardly-extendin g rod B,which slides through a hole formed in the outer end of an arm I,

" serving to prevent rotation of the bell.

extending horizontally from a post I, secured to the outer casing A, and this arm I serves to guide the gasometer in its rise and fall.

I it comes in contact with the lever H, open the Valve H to admit water to the carbidholder. As soon as the water has been admitted through the valve H to the carbidholder generation of gas commences. As soon as this generation of gas is in excess of the consumption the bell B will rise, and thus permit the valve H to close until it has been again opened by the descent of the bell.

The gas is drawn from the gasometer by means of a pipe 0, which extends upwardly through the partition a and also laterally through the outer casing, and there connects with the condenser O. This condenser consists of a cylinder secured to the outer casing A and receiving the gas from the gasometer. The gas is drawn oif from the condenser near its upper end through the pipe 0 To the upper end of the condenser is attached a reliefvalve J, provided with a pivoted lever J, said lever being Weighted, so as to normally hold the valve closed. This weight will be such that the valve will be held closed against any pressure at which it is desired to operate the machine, but will be opened by any increase in pressure. The lever J is also extended toward the gasometer, so that when the bell B rises above a certain height it will engage the lever and lift the valve J, thus allowing the gas to escape and the bell to drop. This is a precaution to prevent the bell from being raised too high or the gasometer from being filledwith gas under a greater pressure than normal.

For convenience in determining the height of water within the gasometer a glass tube A is mounted alongside the outer casing and connected at its lower end to the outer casing A in the manner of'an ordinary gageglass. The tube at its upper end is provided with a funnel through 'which water may be poured to maintain the supply at such levelas desired.

Having thus fully described my invention, I claim as new and desireto secure by Letters Patent- 1. An acetylene-gas machine comprising a generator, a gasometer consisting of a bell I adapted to float in a'wate'r-tank, a valve-controlled pipe connecting the water-tank with the generator, a lever normally holding said valve closed and an arm pivoted upon the bell and adapted to engage the lever to open the valve when the bell descends, substantially as described.
